    Wrote a solution like this:

     const total = n * m;
  let newTotal = 0;
  let support = 0;
  support = Math.floor(n/2) * Math.floor(m/2);
  newTotal = total - support * 4;
  if(newTotal % 2 === 0){
    return support + newTotal / 2;
  }else{
    return support + Math.floor(newTotal / 2 )+ 1
  }

    Then found a solution like this :,)

    let x = Math.ceil(n/2)
let y = Math.ceil(m/2)
return x*y;

      But isnt the answer for n=2, m=4 equals to 3 ? The solution gives 2

    Not sure what I'm doing wrong.

    def gameWithCells(n, m):
    # Write your code here
    total_bases=n*m
    if n==1 or m==1:
        border_drops=total_bases//2
        base_drops=total_bases-2*border_drops
        total_drops=border_drops+base_drops
    else:
        corner_drops=total_bases//4
        border_drops=(total_bases-corner_drops*4)//2
        base_drops=total_bases-4*corner_drops-2*border_drops
        total_drops=corner_drops+border_drops+base_drops
        
    return total_drops
